This patch demonstrates the usage of the alternative method for HSIC devices reset (via the ehci-hcd and omap-ehci drivers, where this method is implemented through a separate patch; must be applied prior to this one). Board functionality is not altered; a minor improvement is the removal of the second call to omap_ehci_hcd_init() after reset which is not needed anymore. On some other OMAP4/5 boards however this is the only method that works.
